The MongoDB backend now supports the MongoDB CLI syntax for native queries. In Neo4j, we have solved a bug related to the way we store embedded collections (OGM-549) and we now create only one relationship for bidirectional associations. We have also worked on the compatibility with WildFLy 8.1.
You can find more details about this release on JIRA.

As always, you can either download a release bundle from SourceForge or retrieve the JARs from the JBoss Nexus repository server using Maven, Gradle etc. The GAV coordinates are:

org.hibernate.ogm:hibernate-ogm-core:4.1.0.Beta4 for the OGM engine and

org.hibernate.ogm:hibernate-ogm-<datastore>:4.1.0.Beta4, depending on the backend you want to use.
